yardscaping
YardScaping
  • A new paradigm?
  • Some call it “Sustainable Landscaping” or “Ecological Landscaping”
  • We want to keep it simple
yardscaping mission
YardScaping Mission
  • To inspire Maine people to
    • create and maintain healthy landscapes
    • through ecologically based practices that
    • minimize reliance on water, fertilizer and pesticides
bayscaping project
BayScaping Project
  • Friends Of Casco Bay did some detective work in 2001, 2002, 2003, 2005 & 2006
  • Sampled runoff water from intensive lawn care areas in Cumberland, S Portland, Westbrook, Falmouth, Yarmouth, Brunswick, Freeport, Portland and Cape Elizabeth & Back Cove area
  • Sampled sediments for pyrethroids in 2006 – All samples were
    • “no detectable levels”
friends of casco bay sampling
Friends of Casco Bay Sampling
  • 2001 Sampling
    • Found Diazinon in 1 of 3 samples (2.6 ppb)**
    • Found 2,4-D in all 3 samples (36.4 ppb)
    • Found Dicamba in 1 of 3 samples (3.8 ppb)
    • Found MCPP in 2 of 3 samples (26 ppb)
    • Found Nitrogen & Phosphorous in all samples
  • 2002 Sampling
    • Found Diazinon in 4 of 11 samples (.71 ppb)
    • Found Nitrogen & Phosphorous in all samples
  • 2003 Sampling
    • Found Dicamba in 3 of 10 samples (4.1 ppb)
    • Found Clopyralid in 1 of 10 samples (0.91 ppb)
    • Found Propiconazole in 2 of 10 samples (0.075 ppb)

**Values in red exceed ALC

back cove project
Back Cove Project
  • 2005 Sampling
    • Found 2,4-D in 2 of 5 samples (4.62 ppb)
    • Found MCPA in 2 of 5 samples (0.45 ppb)
aquatic life criteria
Aquatic Life Criteria
  • EPA criteria for nuisance algae growth
    • Nitrogen - 250 ppb Phosphorous – 20 ppb
  • EPA just proposed diazinon level of 0.1 ppb for fresh water
  • Other criteria proposed by various sources for fresh water (from USGS Fact Sheet 097-99)
    • 2,4-D – 4 ppb Dicamba – 10 ppb
    • MCPA – 2.6 ppb Triclopyr – 560 ppb
    • Carbaryl – 0.02 ppb Chlorpyrifos – 0.001 ppb
usgs national water quality assessment
USGS National Water Quality Assessment
  • Sampled urban streams
    • Insecticides occurred more frequently in urban streams than they did in agricultural area streams
    • Herbicides detected in 99% of Urban stream samples
    • Phosphorous found at same levels as in agricultural streams
      • 70% of those samples exceeded the EPA level for causing excessive algal growth
the tenets of yardscaping
The Tenets of YardScaping
  • Use site appropriate, non-invasive plants
  • Right plant, right place, right purpose
  • Use diversity of plants & grasses
  • Create wildlife habitats
  • Reduce lawn area
  • Use low input lawns & landscapes
  • Use vegetative buffers to protect surface waters
  • Reduce runoff
  • Reduce reliance on pesticides, fertilizers and water
  • Promote sensible pest management (IPM)
use site appropriate non invasive plants
Use site appropriate, non-invasive plants
  • Native plants are well adapted
    • Fewer problems, less work, more rewards
  • Invasive plants are easy to grow but crowd out native vegetation
    • Our local forest habitats are changing rapidly
    • Invasive plants ruin wildlife habitat
right plant right place right purpose
Right plant, right place, right purpose
  • Choose plants based on the area to be planted not just for their color
  • Select plants that thrive under existing conditions rather than trying to alter the conditions to meet the needs of a plant
  • Minimize disturbance of the existing landscape
right plant right place

Common Ninebark – dry sunny site

Right plant, right place

Cinnamon Fern – wet shady site

Staghorn Sumac – large open dry bank

use a diversity of plants grasses
Use a diversity of plants & grasses
  • Less noticeable damage from pests and disease
  • Incorporate many layers of plant types
    • Trees
    • Shrubs
    • Ground covers
    • Perennials, and
    • Lawns
create wildlife habitats
Create wildlife habitats
  • Diversity and plant layers go hand in hand with habitat creation
  • Add nectar and fruit producing plants
  • Strive for continuous blooms
  • Add water, walls, feeders, woody debris
reduce lawn area

Mower exhaust = 40 small cars’ exhaust

Reduce lawn area
  • Reduces
    • Water & air pollution
    • Water usage
    • Maintenance
    • Costs
  • Gives
    • More free time
use low input plant varieties
Use low input plant varieties
  • No-mow fescue vs Kentucky bluegrass
  • Pagoda dogwood vs flowering cherry
  • River birch vs paper birch
protect lakes streams with buffers
Protect lakes & streams with buffers
  • Preserve existing landscape
  • Winding paths
  • Don’t mow to lake’s edge
  • Pitch the rake
reduce runoff
Reduce runoff
  • Reduce amount of pervious (hard) surfaces
  • Create rain gardens or install rain barrels
  • Direct water into vegetated areas
reduce reliance on pesticides fertilizers and water
Reduce reliance on pesticides, fertilizers and water
  • Grow plants that are resistant to insects & diseases
  • Use plants that tolerate low fertility
  • Use drought resistant plants

White Fir

Sweet Fern

use common sense pest management
Use common sense pest management
  • Integrated pest management
    • Know your pest
    • Pick it, trap it or exclude it
    • Know the good bugs
    • Mow, prune or water
    • Use pesticides as last resort
